ASTM A192 (ASME SA192) he paipa maitai waro tui kore te paipa e whakamahia ana i ngā taiao pāmahana teitei me te pēhanga teitei, ā, e whakamahia whānuitia ana i roto i ngā kohua me ngā whakawhiti wera.
Te whānui o waho: 1/2″ – 7″ (12.7 mm – 177.8 mm);
Matotoru o te pakitara: 0.085″ – 1.000″ (2.2 mm – 25.4 mm);
Ka taea hoki te whakarato i ētahi atu rahi o ngā paipa rino e hiahiatia ana, ki te tutukihia ngā whakaritenga katoa o te A192.
Ka hangaia te ASTM A192 mā te whakamahi i tētahi tukanga maeneene, ā, ka oti te whakaoti mā te wera, te whakaoti mā te matao rānei e ai ki te hiahia;
Me whakaata hoki te tohu o te paipa rino mēnā kua oti te whakaoti ki te wera, ki te matao rānei.
Whakaoti wera: E pā ana ki te tukanga whakaoti i ngā inenga whakamutunga o te ngongo maitai i roto i te āhua wera. I muri i te tukanga tukatuka wera o te ngongo maitai pērā i te hurihuri wera, te kume wera rānei, kāore e tukatukahia anō i te makariri. He pai ake te pakari me te ngāwari o ngā ngongo maitai kua oti te whakamahana engari he nui ngā ātete inenga.
Kua oti te makaririKa tukatukahia te paipa rino ki ōna rahinga whakamutunga mā roto i ngā tukanga mahi matao pēnei i te hurihuri matao, te kukume matao rānei i te pāmahana rūma. He tika ake ngā ātete rahinga o ngā paipa rino kua oti te matao, ā, he maeneene ake ngā mata, engari ka ngaro pea te pakari.
Kāore e hiahiatia he maimoatanga wera mō ngā ngongo maitai tui-kore kua oti te whakamahana.
Ka whakamahanahia ngā ngongo maitai tui-kore kua oti te whakamatao ki te pāmahana 650°C, neke atu rānei, i muri i te maimoatanga matao whakamutunga.

Te Pakari o Brinell: 137HBW.
Mō te matotoru o te pakitara o te paipa maitai he 0.2" [5.1 mm] neke atu rānei.
Mō ngā whakaritenga whakahaere motuhake, tirohia te ASTM A450, Tuemi 23.
· Auautanga: Ka whakamātauhia te pēhanga wai ā-pūmau i ia paipa rino.
· Wā: Puritia te pēhanga iti rawa mō te iti rawa 5 hēkona.
· Uara pēhanga wai: I tatauhia mā te whakamahi i te tātai e whai ake nei. Kia mōhio ki te waeine.

Ngā Wāhanga SI: P = 220.6t/D
P = te pēhanga whakamātautau wai ātete, psi, MPa rānei;
t = te matotoru o te pakitara kua tohua, in. mm rānei;
D = te diameter o waho kua tohua, in. mm rānei.
· Hua: Ki te kore he turuturu i roto i ngā paipa, ka kiia kua paahitia te whakamātautau.
Ka taea hoki te whakamahi i tētahi atu huarahi hei whakakapi i te whakamātautau waipū mā te whakamahi i ngā whakamātautau kore-whakangaro e tika ana.
Heoi, kāore te paerewa e tohu ko tēhea tikanga whakamātautau kore-whakangaro ka taea te whakamahi.
Me tū ngā ngongo wera nui ki roto i te pōro, me whānui, me whakapiko, me te kore e kitea he kapiti, he hapa rānei. Ina tika te whakahaere, me tū ngā ngongo wera nui ki ngā mahi hanga, whakarewa, me te piko katoa e tika ana mō te tono, me te kore e puta he hapa.
